1 Switching the instrument ON / OFF Note: The instrument does not have a specific ON / OFF switch. Switching the instrument ON The instrument will switch ON automatically when it is placed on a specimen. If the instrument is placed on nonferromagnetic or electrically nonconductive material, the display will show the error note "Er6" and then four horizontal bars instead of a reading. PLEASE NOTE! Do not power up the instrument by pressing a finger on the sensor! It may result in erroneous measurements.
2 Main Menu – Functional Overview Select the specific sub-menus with [ ] or [ ] and press key [OK].
3 Measurements on coating material Making measurements with the MP0R: 1. With the instrument switched ON, place the instrument on the specimen and wait, until the acoustic signal sounds. The instrument will switch ON automatically this way. 2. Lift the instrument off the specimen. The acoustic signal sounds and the reading will be displayed. Note: when lifting the instrument too early (before the beep sound), the error note "Er6" will appear. In this case, repeat step #1.
Measurement with the MP0R instrument 8
4 Evaluation of a test series (Statistics function) Prerequisite: At least two readings must be saved in the measurement data memory. Note: The measurement data memory must always be empty before starting a test series that is to be evaluated (cf. chapter 6 "Deleting measurements", page 14). If at least two readings are not stored in memory when you first press RES and then [OK], the statistical evaluation will NOT start. Statistical evaluation of a test series: 1. The display menu shows "RES".
Display Explanation Mean value (= arithmetic mean value) s Standard deviation (= mean square deviation of the single readings from the mean value) N Number of measurements in the test series MIN Lowest value in the test series MAX Highest value in the test series Meaning of statistical evaluation data shown in the display.
5 Transmitting data to a computer The RS232 radio interface integrated in the instrument facilitates the transmission of the data stored in the measurement data memory to an optional radio receiver (order no. of US-receiver version: 603-544). The radio receiver, in turn, transmits the data to the evaluation computer via a cable. There is a separate operator's manual for the optional radio receiver. Prerequisite for all following sub-chapters: Settings of service menu must be “rF = 1” e.g.
5.2 Transmitting all measurement data in the instrument memory 1. Set the display menu with [ ] or [ ] to show . 2. Press button [OK]. All readings in the memory are then radioed to the PC. This is indicated by the flashing radio tower symbol. 5.3 Sending the current mean value Prerequisite for following sub-chapters of 5.3: Settings of service menu must be “SI = 0” e.g. mean value transmission is active. See chapter 13 “Service menu, menu #4”, menu mean value transmission”.
5.3.1 Triggering the mean value transmission manually Prerequisite: Settings of service menu must be “bL = 1” e.g. mean value transmission is active. See chapter 13 “Service menu, menu #1”, menu point “Block length”. 1. Make desired number of measurements. 2. Set the display menu with [ ] or [ ] to show "RES”. Press button [OK]. The mean value of the readings in the memory are then radioed to the PC. This is indicated by the flashing radio tower symbol. 5.3.
6 Deleting measurements 6.1 Deleting only the last reading 1. Select the menu DEL with [ ] or [ ]. 2. Press button [OK]. The last reading will be deleted. 6.2 Deleting all measurement data from the measurement data memory 1. Select the menu RES with [ ] or [ ]. 2. Press button [OK]. 3. Select the menu DEL with [ ] or [ ]. 4. Press button [OK]. All measurement data will be deleted from the measurement data memory.
7 Normalizing A normalization is used to adjust the measuring instrument to a measuring task. The symbol on the display of the instrument indicates the “Normalization” operating mode. The following items are required for performing a normalization: • Uncoated specimen. In geometry and substrate material, this specimen should correspond exactly to the parts to be measured. Note: All readings in the memory will be deleted when performing a normalization.
3. Perform about 5 measurements on the uncoated specimen. After each measurement, the current reading will appear on the display. Note: If you want to delete wrong readings, press button [ESC]. Then, the complete data memory will be deleted, but the normalization routine will not be interrupted. After that, perform five more measurements. 4. Press button [OK]. By pressing button [OK], the mean value of all readings will be calculated and used for normalization.
8 Calibration The following items are required for performing a calibration: An uncoated specimen: In geometry & substrate material, this specimen should correspond exactly to the parts to be measured and a calibration standard (instrument-specific correction foil 75 µm (3 mils)). Note: All readings in the memory will be deleted when performing a calibration. Calibrating the instrument (Prerequisite: Instrument must be turned ON) 1. Select the menu with button [ ] or [ ]. 2. Press button [OK].
The mean value is set to zero. The reading 0.00 will appear on the display. The message STD1 (that is, calibration standard # 1) appears. 5. Place the calibration foil on the uncoated specimen and perform about 5 measurements. After each measurement, the current single reading will appear on the display. Note: If you want to delete wrong readings, press button [ESC]. Then, the complete data memory will be deleted, but the calibration routine will not be interrupted.
9 Deleting a calibration / Restoring the baseline of the characteristic Sometimes, if an instrument does not measure correctly even after a calibration, the calibration can be deleted. This can occur if the previous calibration has not been carried out correctly. In such a case, the baseline of the characteristic can be restored to its original factory condition.
3. Perform three to five measurements on the uncoated specimen. The current reading appears on the display after each measurement. 4. Press button [OK]. Note: When pressing [OK], the mean value of all measurements is used as the normalization value. This mean value is set to 0. The display shows 0.00. STD1 (that is, calibration standard # 1) appears on the display. 5. Measure at least two times on the uncoated specimen. A reading will appear. 6. Use button [ ] or [ ] to set the displayed value to 0.00. 7.
10 Setting the specification limits Example: Lower specification limit (MIN): 20 µm; upper specification limit (MAX): 40 µm Setting the specification limits: 1. On the display, set the specification limit mode using the arrow key [ ] or [ ]. 2. Press button [OK]. " - - - " and MIN appear on the display. This means that no values are stored in memory and that the instrument is ready for entering the MIN value; i.e., it is ready to enter the lower specification limit. 3.
6. Measure again once on the specimen (continued on next page!) 7. Set the desired MAX value using the key [ ] or [ ]. Example: the upper specification limit 40 µm. 8. Press button [OK] to accept this value into memory. 9. OFFS appears on the display. At this stage, you can enter an offset value using the key [ ] or [ ]. In the measuring mode, this offset-value will be subtracted automatically from the readings.
11 Deleting the specification limits 1. Switch to the specification limit mode 2. Press button [OK]. The set using the button [ ] or [ ]. value appears on the display. 3. Set the value to "0.00" using the key [ ] or [ ]. 4. Press button [OK] to accept this value into memory. The MAX value will be set to zero with this action. 0.00 will appear on the display. 5. The value can be set to "0.00" using the button [ ] or [ ]. 6. Press button [OK]. The mode will be left.
12 Triggering the group separator The purpose for group separators is to obtain and present data sets in different blocks. In an Excel spreadsheet, the group separator has the effect of writing the succeeding data set into a new column adjacent to the one that has just been processed. Below is a description of the various options for triggering the radio transmission of a group separator of the MP0R instrument. General prerequisites: The setting of the GS menu option in Service Menu #4 must be I, i.e.
1) Automatic triggering of the group separator (with fixed block sizes) Prerequisite: the block size is set > 0. A group separator is sent automatically after the computation of the block statistics (cf. Chapter 4 “Evaluation of a test series”, Page 9) and the subsequent automatic deletion of the data of the block in the measurement memory. 2) Manual triggering of the group separator (without creating a block) Prerequisite: Block size = 0 Obtain any number of measurements. Select using [ ] or [ ].
13 Service Menus Access to the service menues and setting of the service points 1. Select the menu icon using the key [ ] or [ ]. 2. Press button [OK]. “157” will appear on the display. 3. Set “159” using the key [ ]. 4. Press button [OK]. FREE will be displayed. 5. Select the desired service menu number using [ ] [ ] (only service menues # 1, 2, 3, 4 and 10 are active) 6. Press button [OK] repeatedly to select the menu points. Set their current setting using the key [ ] or [ ]. 7.

14 Trouble Shooting Message Er1 Explanation / Possible Cause Internal error Er4 Overflow of the data memory Er5 Cannot determine value for substrate material. Solution Perform a normalization. If the error occurs repeatedly, call the Fischer service dpt. Delete the data memory. Perform calibration on coating using a suitable calibration standard.
Message Er6 Explanation / Possible Cause Reading cannot be displayed since it is out of the measuring range. Cause: coating is too thick. Cause: measurement was not performed correctly Cause: erroneous normalization or calibration Solution Perform measurements on a specimen having a coating thickness measurable by the instrument. Perform measurements correctly (e.g.
- measurement was performed on a the cal. standard instead of the uncoated specimen. - measurement on a creased cal. standard. - measurement was not performed with the instrument placed squarely on the specimen or the calibration standard. Perform all measurements for the normalization using a mean value on the same specimen. Replace calibration standard. Perform all measurements correctly with the instrument placed squarely on the specimen or the calibration standard.
Normalization performed by mistake on calibration standard instead of on uncoated specimen. Perform normalization on uncoated specimen. Er14 Internal instrument error: Not able to compute master characteristic. The original master characteristic is retained. Repeat master calibration. If this error occurs repeatedly: Contact customer service. Er15 Not able to save the master characteristic. Probe may be defective. Contact customer service. Er17 Not enough readings.
